Probably. But I wouldn't charge the guy that was stomping ... assuming the evidence suggests it was in self defense, or in defense of others.
The stomper might not have wanted to retreat, if it would leave the knife attacker free to attack others (family?).
The stomper might not have noticed that the knife had left the girls grip, which could explain his last stomp attempt.
They're teenagers and there obviously is at least 2 groups involved...
Bet each one is blaming the other and each teenager has a different story so that they will not be looked down upon by their peers in the neighborhood.
Another thing...if its the home of a foster parent and the girl shot actually lived their with another foster child...that foster home will never be allowed to foster another child regardless which teen is at fault.
